Ann Tavares, a 46-year-old White mother of four, was killed in her Somerset, Massachusetts, home on July 10, 1991. Her 25-year-old son, Daniel Thomas Tavares Jr., attacked her in his bedroom with a carving knife, stabbing her 26 times. Ann died in the arms of her fiancé, Norman Sirois. A family friend who was also in the house was stabbed during the same incident but survived.

On the day of the attack Ann and Sirois had driven Daniel home from a bar in Tiverton, Rhode Island. Daniel was restrained at the scene and reportedly said he had been hearing voices and had consumed a drink laced with LSD; he had also called his mother at work 23 times that day. Daniel Tavares Jr. pleaded guilty to manslaughter in 1992 and was sentenced to 17 to 20 years in prison. His release in 2007 drew public outrage, and soon after he committed further murders in Washington state and was later convicted in additional cases.

Did anyone in Somerset at the time know about escalating problems between Ann and her son, or have information that wasn’t reported?
